Title: Focus controller
Inventor: HIRASAWA KAZUO
IPC: G02B7/28
Filed: 1980-04-18
Abstract: PURPOSE:To adjust automatically the interval between a condenser lens and record carrier by gradually approximating the interval between the both to the lead-in range where focus control operation is performed, by detecting the interval between the both being beyond the lead-in range. CONSTITUTION:Condenser lens 4 is so located that when focus control is not exercised, the interval between the surface of disk 5 and condenser lens 4 is much greater than a proper distance. In the start of the device, signals from lead-in range detecting circuit 14 to switches 10 and 11 are therefore at L to turn on switch 10 while turning off switch 11. Simultaneously with the start of the device, a start pulse is supplied to lamp waveform generator 12 to develop an output voltage of 0V and this generator 12 is further supplied with pulses from pulse generator 13, so that the output voltage will rise by steps according to the number of those pulses. The output of lamp waveform generator 12 is applied to condenser lens driver 3 via condenser lens driving circuit 2 to move condenser lens 4 gradually, which approaches disk 5.

Title: Attaching structure of fitting metal block to building materials
Inventor: ISHII TAKURO
IPC: E04F13/08
Filed: 1991-03-18
Abstract: PURPOSE:To make constant and small a restraint force to the face acted on a panel. CONSTITUTION:When a fitting metal block 4 is attached to a panel 1 with a bolt 7 through a slide washer 6, a cylindrical metal 8 is fitted to the bolt 7 and the head of bolt 7 is forced to contact the cylindrical metal 8 when the bolt 7 is screwed in. In this way, since the frictional force toward the face between the panel 1 and the fitting metal block 4 is not almost brought about, the restraint force to the face acted on the panel 1 becomes constant and small. And hence, the panel 1 is prevented from damages.

Title: Photoelectric switch
Inventor: TANIGAWA KIYOSHI
IPC: H03K17/78
Filed: 1988-03-08
Abstract: PURPOSE:To prevent malfunction from being performed by reducing a possibility in which another photoreceiving signal is fetched in an AND gate by emitting a differentiation signal only in a short time at the time of rising a digital signal via a differentiation circuit after performing the level-discrimination of a photoreceiving signal and converting to the digital signal. CONSTITUTION:The differentiating circuit 10 is inserted between a comparator 7 and the AND gate 8. The circuit 10 is consists of a shift register in which two D-FFs 11 and 12 are cascade-connected and an AND circuit 13. When the differentiation signal (g) of the output terminal of the circuit 10 synchronizes with a frequency division pulse (b), an output pulse e2 from the AND gate 8 goes to a high level. A signal equivalent to an output pulse (en) by light from the outside is eliminated since the differentiation signal (gn) is not synchronized with the frequency division pulse (b). Therefore, the output signal f2 of a detecting circuit 9 can be set at a low level surely at a time t5. In such a way, the malfunction of an output signal can be prevented from being performed.

Filed: 1989-03-07
Abstract: PURPOSE:To execute the measurement with high accuracy by measuring the capacitance between a conductive body part of a probe and an object to be measured in an insulated state. CONSTITUTION:A die 1 being an object to be measured is placed on a stone surface plate 40. In this state, since a probe 13 and the die 1 constitute a capacitor as both electrodes, the capacitance of the capacitor is measured by a multimeter 30. Subsequently, when a spindle 12 of an inching device 20 is allowed to descend and the probe 13 is brought close to the die 1, the capacitance is displayed on the multimeter 30. In this state, the die 1 is moved on the surface plate 40, and the die 1 is fixed to a position in which a capacitance value shows the maximum value. Thereafter, when the spindle 12 is allowed to descend by the device 20, the capacitance value shown on the meter 30 increases like a hyperbolic curve function. In this case, when the probe 13 comes into contact with the die 1 by allowing the spindle to descend, while confirming the capacitance value by the meter 30, the capacitance value shown on the meter 30 becomes infinite. Accordingly, by confirming the capacitance value shown on the meter 30, the contact of both of them is predicted.
